Once again, Jiri and Ilpo have done a number of core vt and tty/serial layer cleanups that were much needed and appreciated. Other than that, it's just a bunch of little tty/serial driver updates: - qcom-geni-serial driver updates - liteuart driver updates - hvcs driver cleanups - n_gsm updates and additions for new features - more 8250 device support added - fpga/dfl update and additions - imx serial driver updates - fsl_lpuart updates - other tiny fixes and updates for serial drivers All of these have been in linux-next for a while with no reported problems.
